BLAUBERG WKH Water Duct Heater
Introduction
The present operation manual is combined with technical specification, operating instruction, certificate, information on installation. Device: Water duct heater WKH (further in the text “WKH”)
Function
Device WKH with water as heat carrier and round or rectangular connection to
the air duct is designed for heating of air in the air-conditioning,
ventilation and hot-air heating systems and in drying units and warm air
curtains.
Delivery set contains:
- device WKH – 1 piece
- operation manual – 1
- piece packing box – 1 piece
Technical specifications
WKH devices are used in enclosed spaces at ambient air temperatures from +1 °C
to +50 °C. Maximum temperature: 100 °C, maximum pressure at 100 °C : 1.6 MPa
(16 bar).
WKHs are designed for exploitation in area with moderate and cold climate (UHL
3 by GOST 15150-69).
Design and principle of operation
Design of WKH with rectangular and round connecting to air duct (Picture 1 and
Picture 2) consists of the case (1) and the heating element (3) built in the
case. The case consists of the wall (6 for round ducts), two protective
casings (2) manufactured from high-quality galvanized steel.
Heating block is a package of two or four rows of copper tubes with aluminum
ribs set on them, and copper unions. The tubes are joined in groups the ends
of which soldered in manifolds made from copper pipes through which the heat
carrier goes in and out.
For connecting to the external system the manifolds have special unions on the
butt end of the heating block providing threaded connection. The output
manifold has a nipple with thread (G1/4) with a plug (place Л on Picture 1 and
Picture 2), instead of which an immersion sensor may be placed for measuring
the temperature or for protection from freezing. There is also a air-relief
nipple with thread G1/2 (4), a water-drain nipple with thread G1/2 (5) from
the butt end of WKH.
The air is heated during its passage through the heat exchanger
in the process of interaction with copper tubes and aluminum plates. All
heaters are tested for leaktightness at maximum working pressure of 1.6 MPa
and water temperature of 100 °C. Connection dimensions correspond to
connection dimensions of elements of duct ventilation (duct fans, electric
duct heaters, duct noise mufflers, etc.)
For WKH a surface mount sensor is possible to apply instead of immersion
sensor.
Water heaters are supplied without temperature sensors and frost protection.
To avoid emergency situations during exploitation of WKH, please provide the
water flow excluding a possibility of freezing of WKH.
Basic parameters and dimensions
Basic dimensions of WKH with round and rectangular connecting to the air duct
must correspond to the values listed in tables 1, 2 and on Picture 1 and
Picture 2. Basic parameters and technical specifications are listed in tables
3, and 4.

Safety requirements
Requirements of the present operation manual, Rules of safe operation of
consumer’s electric devices, current building norms and rules, Rules of fire
safety in Ukraine shall be observed during installation and operation of WKH.
Before starting the NKV please make sure there are no visible damage of the
device, no foreign objects in the duct or leaks in the joins.
Warning!
Do not use a WKH for work with explosive dust air mixture.
Warning!
Damage of copper pipes (deformation and breakup) may occur in the heat
exchanger at freezing of water. As a result, leakage of water from the heat
exchanger circuit will occur and the heater will be out of order.
Exploitation of the device beyond the temperature range specified in the
operation manual and in rooms with the air containing aggressive admixtures is
forbidden.
Installation
Installed directly in the air ducts in the positions that make possible to
join connecting pipes in horizontally, from the side of a WKH or vertically
from above.
Connection of pipes vertically from below is impermissible. Water duct heater
may be of right or
left executions depending on the customer’s request. When water is used as the
heat carrier, the heaters shall be used in rooms where temperature is above 0
°C.
The heater shall be installed in the air ducts of the similar diameter (size).
Operating position of the heater shall ensure free access for service
maintenance, for joining of pipes with heat carrier.
It is recommended to install the air filter in front of a WKH in the direction
of air flow.
A water heater may be installed in front of or behind the fan.
If a NKV is placed in front of a fan, its capacity must be adjusted so that
the air temperature inside The fan does not exceed the maximum permissible
value.
Rules for storage and transportation
Keep NKV in the original package in a closed room at temperature from 10 °C to
+40 °C and relative humidity not exceeding 80 % (at temperature of 25 °C).
Presence in the air of steam and admixtures causing corrosion and failure of
isolation and leaktightness is not admitted. Transportation by any mode of
transport is possible on condition of protection from atmospheric
precipitation and mechanical damage. Loading and unloading must be performed
avoiding. Any bumps and pushes.
MANUFACTURER’S GUARANTEES
Manufacturer Closed joint-stock company “Blauberg” guarantees that WKH
complies with technical specification subject to observing the installation
and operation, storage and transportation rules. Guaranty period of
exploitation is 24 months from the date of sale through the retail network. In
case of absence of a note about the date of sale, the guarantee period shall
be calculated from the date of manufacture. The guarantee becomes invalid in
case a WKH has damages because of the use of the device with the purpose other
than it was designed for and because of rough mechanical interference with the
device.
